Catalytic Transfer Hydrogenation of Castor Oil
Journal of Chemical Education, 2014The main thickening agent or soap in multipurpose grease, lithium 12-hydroxystearate, is a chemical commodity for the auto industry. This compound is obtained from castor oil via a series of chemical transformations. The first step, hydrogenation of castor oil, has been developed into a laboratory experiment for second-year undergraduate organic ...

Cutaneous anaphylactoid reaction to polyoxyethylene hydrogenated castor oil in dogs
Veterinary Dermatology, 2023AbstractBackgroundPolyoxyethylene hydrogenated castor oil (HCO ethoxylates) is a nonionic surfactant used as an excipient for ointments and injections in human and veterinary drugs. Several polyethylene glycol (PEG) derivatives can be obtained depending on the number of moles of ethylene oxide (EO).

Low pressure hydrogenation of castor oil
Journal of the American Oil Chemists' Society, 1988AbstractCastor Oil was hydrogenated at low pressure (2.0–2.5 kg/cm2) and low temperature (125–135 C) using nickel catalyst to obtain a saturated waxy product rich in hydroxy stearic acid. High catalyst concentration was required to obtain good results. However, the catalyst could be recycled. The final product had iodine value below 3.0, hydroxyl value

Effect of agitation in the hydrogenation of castor oil
Journal of the American Oil Chemists' Society, 1997AbstractCastor oil was hydrogenated to evaluate the effect of agitation during hydrogenation. The turbine and propeller impellers were evaluated during hydrogenation of castor oil at various temperatures, pressures, and catalyst concentrations. The effect of impeller position in the agitator at definite oil depth was also evaluated.

The hydrogenation of fatty oils with palladium catalyst. I. Hydrogenation of castor oil
Journal of the American Oil Chemists' Society, 1958SummaryA good quality of castor wax was prepared in the laboratory at 100°C. and 45 p.s.i.g., using a modified palladium catalyst. The product obtained had an iodine value of 4, a hydroxy value of 145, and acid value of 1.8, and a capillary melting point of 86°.

Journal of Applied Polymer Science, 1966
AbstractAlkyds prepared from castor and hydrogenated castor oils have been prepared direct from the oil and by first subjecting the oil to a glycerolysis reaction. The molecular weight distributions of the alkyds have been measured in solvent systems designed to separate predominantly on polarity and molecular weight.
